Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

friendlyenergeticaffordablesocial

Orange is red with the aggression taken out — approachable, active, and strongly associated with buying and doing.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. The low lightness adds weight and formality.

Worth knowing

Hard to make feel premium, and it collides with the "caution" band in status systems.

What each alpha value actually composites to. The top row is #513e21 over white; the bottom row is the same alpha over a checkerboard, so you can see what survives on a photo or a video.

Bottom row of hexes is the flattened result over white — use those when a design tool refuses transparency, or when you need a solid fallback.

#513e21, answered

What color is #513e21?

#513e21 is a deep soft orange, closest to Saddle Brown (ΔE2000 16.2). It sits at 36° on the hue wheel with 42% saturation and 22% lightness, which reads as warm.

What is the RGB value of #513e21?

rgb(81, 62, 33) — 81 red, 62 green and 33 blue out of 255, or 31.8% / 24.3% / 12.9% by channel.

What is #513e21 in HSL and HSV?

hsl(36, 42%, 22%) and hsv(36, 59%, 32%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #513e21 a light or a dark color?

It is a dark color. Relative luminance is 0.0530 and perceived brightness is 26%, so white text on it reaches 10.19:1.

Should I use black or white text on #513e21?

White. It scores 10.19:1 against #513e21, versus 2.06:1 for black — AAA at any size.

Is #513e21 accessible on a white background?

#513e21 on white scores 10.19:1, which clears AAA at every size.

What is the complementary color of #513e21?

#213451 sits directly opposite on the wheel. Softer options are the split-complements #214C51 and #262151, which give the same contrast with far less vibration.

What colors go well with #513e21?

For interface work: #FAF8F4 as the surface, #E7DAC5 for borders, #9B7B4B for secondary text, #1F4153 as an accent and #5B4525 for hover and pressed states. For a palette, the analogous pair #512621 and #4C5121 stays calm, while #213451 is the loudest partner.

What is #513e21 in CMYK for printing?

cmyk(0%, 24%, 59%, 68%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #513e21 warm or cool?

Warm — it scores 5 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #513721; nudged cooler, #525120.

Which Tailwind color is closest to #513e21?

The stone family — its 500 step is #78716c, ΔE2000 20.8 away. That is a visible difference, so define #513e21 as a custom token rather than reaching for the built-in.

How do I use #513e21 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#513e21] or text-[#513e21], or register the whole ramp under theme.extend.colors.brand so you get bg-brand-500 and friends. The generated 50–950 scale on this page is ready to paste into your config.

What is #513e21 with 50% opacity?

rgba(81, 62, 33, 0.5), or #513e2180 in eight-digit hex. Over white that composites to #A89F90; over black, #291F11.

Is #513e21 a web-safe color?

No. The nearest web-safe colour is #663333, ΔE2000 19 away. The palette only matters for legacy displays and some email clients now.

What does the color #513e21 mean?

As a orange, it reads friendly, energetic, affordable. Orange is red with the aggression taken out — approachable, active, and strongly associated with buying and doing. At this moderate chroma the association is present but not shouted.
